T0 to whom, it may concern.-

Be it known that I, CARL J. A. SJOBERG, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in Buttonl lole Attachments; andl do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to simplify and cheapen theconstruction, and at the same the head of the machine being shown toillustrate the mode of attachment thereto; Fig. 2, a plan view of theoperative parts, the cap be- 'ing in section, the position being at thebeginning or ending of a button-hole; Fig. 3, a longitudinal section onthe line 00 as in Fig. 2; Fig. a, a plan view corresponding with Fig. 2,except that the parts are in position just after the first turn-that is,at the beginning of the last half of the button-hole; Fig. 5, a1ongitudinal section on the line 3 y in Fig. 4; Fig. 6, a frontelevation of the attachment; and Fig. 7 a rear elevation thereof, theparts being in the same position as in Figs. 1, 2, and

3; Fig. 8, a plan view, the position of the parts being the same as inFig. 2, except that the feeding mechanism is removed; Fig. 9, a similarview to Fig. 8, showing the parts in the saine position as in Fig. 1;Fig. 10, a plan View corresponding with Figs. 2 and 8, the feedingmechanism and cloth-clamp being removed; Fig. 11, a similar view to Fig.10, the position of the parts corresponding with Figs. 4: and 9; Fig.12,an inverted plan View of the attachment complete; Fig. 13, a View of thecrossslide detached; Fig. 1 1, an inverted plan View of the ratchet foroperating the cross-slide detached; Fig. 15, a view of the cloth -clampspring detached; Fig. 16, a longitudinal section of a portion of thecloth-clamp, showing the manner in which the length of the buttonhole isadjusted; Fig. 17, a side elevation of the forward end of thecloth-clamp and the work-holder, showing the manner in which the clampis attached in place; Fig. 18, a side elevation of the frame-work, allthe operative parts being removed; Fig. 19, an elevation of the cuttingmechanism detached; and Fig. 20 is a view of the cutter detached.

The frame-work of the attachment, consisting of bed-plate 1,side pieces2, and standard 3, is struck out and formed from a single piece ofmetal.

1 denotes the oscillating work-carrier; 5, the feed-rack, which is madeintegral with or secured thereto; 6, the feed-pinion which en-- gagessaid rack, and 7 the feed-wheel with which the feed-pinion is madeintegral or to which it is secured. It will be noticed (see Figs. 3, 4,and 5) that the edge of the feedwheel is provided with two rows or setsof teeth which are inclined in opposite directions. The upper row I havedesignated by 8 and the lower row by 9;

1O denotes the reversing-plate, and 11 a screw-pin securing thefeedewheel thereto, all

of which will presently be more fully explained.

12 denotes the feed-plate, which slides in ways 13 in the side pieces ofthe frame-work, lugs 14 being provided to engage these ways. This plateis struck out and formed from a single piece of metal, and lugs 15 atthe opposite ends of the plate are turned downward at right anglesthereto, forming bearings which hold the plate securely in its operativposition.

16 denotes the feed-pawls, which are placed one above the other, and aresecured by a screw-pin 17 to the feed-plate. It will be seen in Fig. 7that one of these pawls engages the upper row of teeth, the other thelower row. The ends of both pawls are provided with downwardly-turnedlugs 18, which engage openings 19 in the feed-plate to limit the motionof the feed-pawls. A spring or pair of springs 20, engaging the backs ofthe feedpawls, acts to force them both inward, so that each is inposition to engage its corresponding set of teeth in the feed-wheel atthe proper time.

21 denotes the feed-slide, which is provided with rack-teeth 22, whichare engaged by rackteeth 23 on feed-lever 24.

25 is an operating-lever, which is provided with the ordinary slot 26 toengage the needlebar of the machine. The operating-lever and thefeed-lever are both secured to the standard by a screw-pin 27. The upperend of the feed-lever is provided with a flange 28 and set-screws 29,the points of which bear against the operatinglever to limit thevibration thereof, so as to adapt the attachment to different styles ofmachines.

30 is a plate made integral with or secured to the feed-slide and whichis provided with a pin or lug 31, engaging slot 32 in the feedplate,whereby motion is imparted to the latter.

33 denotes the cross'slide which operates the oscillating and shiftingmechanism. This cross-slide moves in openings 33 in one of the sidepieces of the standard, and is provided with an opening 34, said openingbeing provided on opposite sides with cam-surfaces 35. This cross'slideis operated by means of a cam 36 upon the under side of a ratchet 37.This cam lies within opening or yoke 34:, and is ordinarily madethree-sided, as shown in the drawings, the cam and cam-surfaces 35 beingso laid out relatively to each other that each actuation of the ratchetthrows the crossslide to one extreme or the other of its move ment. Forinstance, to move it toward the right, one of the points 33 of the cam36 would engage the right cam-surface 35, as the plate lies in themachine, and one of the sides 39 of cam 36 would be in contact with theleft camsurface 35. To move the slide toward the left, one of the pointswould be in contact with the left cam-surface and one of the sides incontact with the right cam-surface. Cam 3G is actuated by a pawl 40,carried by feedslide 21.

4:1 denotes a spring acting to hold this pawl in engagement with theratchet. The respective positions of this pawl in actuating the ratchetare shown in Figs. 2 and 4: and in Figs. 8 and 9.

42 denotes an oscillating lever carrying a double pawl 43 at its forwardend, the functions and operation of which will presently be explained.This link is secured to the cross-slide by a pin 44:, and its rear endis socketed in a recess 45 in the bed-plate of the attachment. Theoscillatory motion of the work-carrier is imparted through thecrossslide.

46 is a screw-pin which passes through a slot 47 in the work-carrier andengages 1101c 48 in the cross'slide. The reversing-plate 10 is providedat its rear end with a slot 49, which engages a stump 50 upon a plate51, adjustably secured to the bed-plate.

52 is a friction-spring secured to the bedplate and bearing on thereversing plate to hold it in operative position.

53 is a slot in the reversing-plate engaged by a pin 54, projectingupward from the bedplate, whereby the plate is held in position oppositesides of the V-shaped teat or projeetion, thus acting to hold either endof the pawl in engagement with its respective set of racleteeth upon theend of the reversing-plate.

It may be here observed that the pivotal point of the work-carrier 4 (orthat point on which it swings laterally to enable the overedge orbutton-hole stitches to be produced) is coincident with the feed-pinion6, said workcarrier having a pivotal connection with the cross-slide 33,which imparts the lateral oscillating movements to said work-carriernecessary for the production of the overedgc stitching, the bearingshoulders or disks 6G and (37, (hereinafterreferred to,) which hold thepinion 6 and rack 5 in engagement with each other, being concentric withsaid pinion.

As the pinion 6 and feed-wheel '7 are mounted on the pivotedreversing-plate, it is obvious that they will be moved laterally withthe said plate when the latter is swung one way or the other, suchlateral movements of the feedwheel and pinion and of the shoulders ordisks 66 and G7, rigidly connected to and thus movable therewith,serving to give a suflicient lateral throw to the forward or work-clampend of the said feed-plate to form the barringstitches at the ends ofthe button-holes and to bring the woikinto proper position beneath theneedle of the machine to work the second side of a button-hole after thefirst side thereof has been worked, or to bring the work-clamp into itsinitial position for the working of a new button'-hole after the secondside of a button -hole has been worked, such lateral movement beingknown as the shipper movemcnt,in contradistinetion to the vibrating orover-stitch movements.

The stump or projection 50, which extends into the slot. 49 of thereversing-plate, serves as a fulcrum forsaid plate, or as a pivotalpoint on which said plate will swing when operated by the pawl 43 ineffecting the shipper or ship-over movements of the work-carrier. Byloosening the screw by which the plate 51 is secured to the bcd'plate 1the said plate 51 may be moved to adjust the fulcrum projection 50 in orout of the slot 49, and by thus changing the position of the saidfulcrum the shipper movement may be regulated to vary or adjust thedistance apart of the lines of IIC ' feed-rack 5 upon the work-carrier.

feed-slide.

stitches forming the workedbutton-hole,as may be required.

The operation of the parts already described .is as follows: Each upwardor downward is caused to reciprocate through the engagement of pin 31with slot 32 in the plate, so that each reciprocation of the feed-levercauses a reciprocation of the feed-slide and the feedplate. At thecommencement of each buttonhole the parts are in the position shown inFigs. 2, 8, and 10. The reversing-plate is; swung toward the right, asin Fig. lO-thatis, looking from the front of the machine, asin Fig. 6.This of course swings the feed-wheel toward the right and brings theright feedpawl in engagement with its corresponding set of teeth uponthe feed-wheel, the under set, as shown in the drawingsthat is, the setthe action of which is to move the work-cal rier forward, as in Fig. 2.It will of course be understood that the feed-plate is recessed out toafford ample room for the movement of the feed-wheel, the recess beingindicated by 59, (see dotted lines in Figs. 2 and 4,) the other dottedline in these figures denoting openings through the cap. (Shown also inFigs. 3 and 5.) This capis denoted by. 61, and is secured in anysuitable manner to the side pieces. As the feed-plate reciprocates inits bearings, it follows that each forward movement thereof will causethe right feed-pawl to impart a forward movement to the feedwheel. Whenthe plate moves backward, the pawl slips over the teeth in the usualmanner, rc-en gaging the teeth again at the end of the backwardmovement, ready to carry the wheel forward again with the next forwardmovement of the feed-plate. As the feedpinion and feed-wheel movetogether, it follows that the work-carrier must move forward through theengagement of the pinion with The 05- cillation of the work-carrier,whereby the cross-stitching of the button-hole is produced, isaccomplished by the movement of the cross-slide, to which it is pivoted,as already explained. Each forward movement of the feed-slide causespawl 10 to engage ratchet 37 and impart a movement thereto, which,bymeans of cam 36 and cam-surfaces 35 upon the cross-slide, imparts tosaid slide a movement in one direction or the other. While thework-carrier is moving. forward the right point of double pawl 43 restsupon the smooth surface 62 at the end of the reversing-plate between thetwo sets of rack-teeth 55 and 56, as in Fig. 10, said pawl and thereversing-plate being inoperative during this? forward movement. Theforward movement continues until the end of the button-hole As alreadystated, feed-plate 12- is reached, at which instant stump'63 upon theunder side of the work carrier engages lug 64 on the double pawl 43,tripping said pawl and bringing the left point thereof into engagementwith the left set, of ra-ck teeth at the rear end of thereversing-plate, (denoted by 56.) It will be seen that spring 58, whichengages teat 57 on the double pawl,

, acts to hold it in either position into which it may be thrown, andthat friction-spring 52 acts to hold the reversing-plate in position, sothat at each movement of the cross-slide toward the right the left pointof pawl 43 will slip backward over one of the rack-teeth in set 56. Themovement of the cross-slide toward the left of course carries lever 42and double pawl 43 in that direction, so that through the movements ofthe cross-slide, link, and pawl the reversing-plate is quickly movedfrom'the position shown in Fig. 10 to that shown in Fig. 11, whichcompletes that end of the button-hole. As soon as the reversingplate andthe left point of pawl 43' have reached the position shown in Fig. 11'they bot-h become inoperative again. While these movements of thereversing-plate have been taking place the feed-wheel has of course beeninoperative, as neither feed-pawl'has been in engagement therewith. Assoon as the movement of the reversing-plate is com- .pleted and the leftpoint of the double pawl engagement with the other row of teeth-in thepresent instance the upper row-in the feed-wheel, as in Fig. 4a Thisreverses the movement of the feed-wheel, and consequently of thefeed-pinion, so that the work-carrier begins 7 to travel backward tocomplete the other side of the button-hole. The movement down the otherside of the button-hole continues-until adjustable stump 65 upon theunder side of the work-carrier comes in contact iwith lug 6i on thedouble pawl 43, which trips it again and brings the right point thereofin. engagement with the set of teeth 55 at-the forward end'of thereversing-plate. The action in reversing is the same as before until theright point ofpawl 43 has acted upon each tooth in set 55 in turn, fromthe outer one inward, which completes the other end of the button-hole,the parts being again in the position shown in Figs. 2, 8, and 10. It isof course preferable .to run a few stitches over the point at which thestitching comin slot 68 at the rear end of the work-carrier over theedge of the rack and the upper one .side of the feed-wheel, the lowerone resting resting in a recess 59 in the feed-plate. These shouldersserve as bearings and hold the parts firmly in position in use. i

It will be noticed in Figs. 2 and 4 that a gage G9 is provided upon thetop of the feedwheel, and in Figs. 4 and 8 that a gage 70 is providedupon the top of the work-carrier by the side of slot 71. Stump 65 uponthe under side of the work-carrier is made adjust able by means of setscrew 72, which passes through slot 71 and engages said stump. The adjustinent of this stump determines the point at which the second crossingorbarring of the button-hole takes place-that is,- the point at whichthe second movement of the reversing plate takes place. The attachmentillustrated in the drawings is capable of producing aninch-'and-a-quarter button-hole for its larger size.- If a button-holeof this size is desired, set-screw 72 is loosened and the stump pushedto the extreme forward end of slot 71. If a half or three-quarter inchbutton-hole is desired, the stump is set to the proper position,- asindicated by gage 70, in order to make the second crossing, barring, orturn at the proper time. The position of the work-carrier and clothclampwhen commencing to work the buttonhole is determined by the adjustmentof the feed-wheel, which is provided with a fingerknob 73,forconvenience in operation, this finger-knob being always within reachthrough the opening in the cap. (See Fig. 3.)

7i (see Fig. 5) denotes aprojection or point in the edge of openingthrough the cap, which is the mark used to determine the position inwhich the feed-wheel is to be set when abutton-hole of a certain lengthis to be made, as determined by the position of adjustment of theadjustable stump (i5.

Supposing it is desired to make a half-inch buttouhole, the parts beingof course in the position shown in Figs. 2,- S, and 10, the feedwheel ismoved forward until the point 'marked one-half on gage 69 is brought inline with projection 74, when the machine may be started. it As statedabove, While either point of double pawl 43 is acting upon thereversing-plate, both feed-pawls are out of engagement with the feed-wheel; consequently no forward movement of the work-carrier takes placeuntil movement of the reversing-plateis completed, so as to bring thefeed-wheel into position to be engaged by the other feed-pawl.

hen the attachment is not in place upon the machine, the work-carriermay be readily moved backward or forward by rotation of the feed-wheelby hand. In order, however, to prevent the work-carrier from moving farenough in either direction to allow either of the stumps 63 or toforcibly engage lug 64 on the double pawl, and thus prevent thereversing mechanism from acting, I have provided a stop 75, preferablymade integral with friction-spring 52, which engages shoulders 76 in theedge of the workcarrier, thereby limiting its movementin both directionsand avoiding the possibility of either stump moving far enough toanything more than trip the double pawl, thus preventing injury to thereversingmechanisin.

7 7 denotes the needle-hole in the bed-plate. The forward end of thework-carrier is of ordinary construction, and is provided with the usualopening 78. H

79 is a cloth-clamp having flanges 80, which extend down into thisopening," thus holding the work firmly, and rearwardly-extending arms81, which are joined by a cross-piece 82.

83 denotes lugs which project downward from the cross-piece, and areprovided with notches 84, adapted to engage projections 85 on the edgeof the work-carrien I I 86 denotes a standard projecting upward from thework-carrierbetween arms 81 of the cloth-clamp. A j

87 denotes a clamping-lever pivoted to the standard. The head of thislever has two straight faces, one of which is continuous with the handleand the other at right angles thereto,the face in line with the handlebeing at a greater distance than the other from the pivotal point, sothat when the handle is turned downward the cloth-clamp is pressed downupon the work-carrier, flanges 80 passing into opening 7 8. \Vhen theother face of the clamping-lever is in contact with the clothclan1p'thatis, when the'handle is in the raised position, as in Fig. 17-thecloth-clamp is raised above the Workcarrier by the action of a spring 88lying under said carrier. Any style of spring may of course be used forthis purpose, although I preferably make a special spring having a plate89, with a slot 90, adapted to engage the standard. The spring, beingsimply slipped over the standard, is held firmly in position at alltimes without the use of rivets or screws.

In order to provide simple and convenient means for cutting thebutton-hole after it has been stitched, Ihave devised a cuttingmechanism adapted to be used in connection with the needle bar, cap, andstandard 86, which I will now describe.

91 (see Figs. 2 and 19) denotes a plate substantially' a right angle inform, which is provided with a slot 92,- adapted to engage standardSiiabove clamping-lever 87 when it is in the locked position, withneedle-holes 93, to adapt it for different button-holes, differentmachines, 850., and a rearwardly-extending shank 94:,- which is bentdownward and rests in a loop 95, formed integral with the cap, asclearly shown in Figs; 6 and 7.

96 (see Figs. 19 and 20) denotes a cutterblade, the edge of which ismade of just the required length to cut the special length ofbutton-hole that is being stitched.

Plate 91 is provided with a downwardlyprojecting flange 97, the ends ofwhich are curved around, forming sockets which embrace the cutter. Thecutter is firmly secured in place by a set-screw 98, which passesthrough slot 99 in the cutter and engages flange 97. V

The operation is as follows: The cutter has tobe placed in position foreach button-hole;

but as there are no adjustments it takes but an instant to do so. Theshank simplyhas to be slippedwinto loop 95 and the plate passed over thestandard which engages slot 92. To cut the button-hole, the flywheel ofthe inachine is moved by hand, which of course brings the needle-bardown and causesthe end thereof denotedby 100 to engage the top of plate91 on opposite sides of the special hole through which the needlepasses. This of course forces the cutter down and cuts the button-hole,

101 denotes the slot in the bed-plate through which the cutter passes incutting a buttonhole. Itshould be noticed (see Figs. 11 and '12) thatthis slot is placed at one side of the needle-hole in the bed-plate, andis wholly independent thereof. The slot is made long enough toaccommodate any length of buttonhole, and no changes in the attachmentare required in cutting different lengths. The cutting is of course donewhen the needle-bar is down, at which instantthe work-carrier isoscillated toward the left, as seen in Fig. 2, so that the cutter-bladeenters said slot without interference with any part of the machine orattachment.

In use the attachment is secured directly to the rear slide 102 of themachine. V

103 (see inverted plan View, Fig. 12) denotes screws which passthroughzthe slide from beneath and engage the bed-plate 1 of theattachment.

104 denotes a longitudinal slot in the slide which curves out to theedge thereof, forming a strip 106.

105 denotes a set-screw which passes through the bed-plate of theattachment, the point of which engages the outer side of slot 104,acting to spring strip 106 outward against the slide-groove (not shown)in the bed-plate of the machine, thus locking the attachment firmly inplace.

The operation of the attachment is briefly as follows: The rear slide ofthe machine is taken out and the attachment secured thereto. The slideis then pushed into place and locked there by set-screw 105. Thefeedwheel and adjustable stump upon the under side of the work-carrierare adjusted to the proper length of button-hole, the work placed inposition under the cloth-clamp and secured there by the clamping-lever.The operation of stitching the opposite. sides of the button-hole andbarring the two ends and the movements of the parts in accomplishingthis result have been so clearly described as not to require repetition.\Vhen a buttonhole is completed, the cutter, without disturbing any ofthe parts, bya single movement of the fly-wheel, is caused to cut thebutton-hole. The cutter is then removed, the cloth-clamp lIaving thusdescribed my invention, I
